Abstract

A laterally flexible and generally longitudinally inflexible hand-held sanding device. The device includes a generally tubular thick walled body of tough rugged semi-rigid resilient material which is generally cylindrical through about three-fourths of its periphery. An angular extension projects from one side of the generally cylindrical body, defined by intersecting flat tangential faces. A longitudinal slit extends the length of the body bisecting the angular extension and, with the tangential faces defining a pair of closely spaced apart adjacent symmetrical parallel angularly and outwardly extending tapered lips. The sander may be flexed to accommodate a variety of contours to be sanded. It may be used in association with sheets of sandpaper or other abrasive material, or abrasive material may be embedded in the body of the sander, either at the surfaces thereof or throughout the body.

Dependent claims

A hand-held sanding device which is laterally flexible and relatively inflexible longitudinally, capable of slight longitudinal deformation under normal manual working pressure, which device consists of:

A) a hollow generally tubular thick walled body of tough rugged semi-rigid resilient rubber or rubber-like material, said body being generally cylindrical through about three-fourths of its periphery in its normal relaxed at-rest state, and having a generally cylindrical generally closed passage throughout its length,
B) an angular extension projecting from one side of said body, said extension being defined by a pair of flat outer intersecting tangential faces;
C) a longitudinal radial slit extending the length of said body from said generally cylindrical passage to the intersection of said tangential faces and bisecting the angular extension, the flat surfaces defining said slit being relatively wide extending from the outermost tip of said angular extension to the inner tubular wall of the body, said flat surfaces being parallel and closely spaced apart, adapted to grip a sheet of sandpaper or other abrasive sheet material therebetween, and
D) a pair of closely spaced apart adjacent parallel angularly and outwardly extending symmetrical mirror image tapered lips on opposite sides of said slit and between said tangential faces.

A) a hollow generally tubular thick-walled body of tough rugged semi-rigid rubber or rubber-like material,
1) said body being generally cylindrical through about three-fourths of its periphery in its normal relaxed at-rest state, and having a generally cylindrical generally closed passage throughout its length,
2) said body being between about 11/2 to 4 inches in diameter, and about 11/2 to 8 inches in length, and
3) said wall thickness being between about 3/16 to 1/2 inch,
B) an angular extension projecting from one side of said body, said extension being defined by a pair of flat outer tangential faces,
C) a longitudinal radial slit extending the length of said body from said generally cylindrical passage to the intersection of said tangential faces and bisecting the angular extension, the flat surfaces defining said slit being relatively wide extending from the outermost tip of said angular extension to the inner tubular wall of the body, said flat surfaces being parallel and closely spaced apart, adapted to grip a sheet of sandpaper or other abrasive sheet material therebetween, and
D) a pair of closely spaced apart adjacent parallel angularly and outwardly extending symmetrical mirror image tapered lips on opposite sides of said slit and between said tangential faces.
